Description
Simple disjunctive decomposition f(X, Y)=h(g(X), Y)is a special case of a functional decomposition, which offers an optimum circuit structure for a single-output logic function. This paper presents a method for improving combinational circuits by applying the above decomposition when exists a function f represented by a given multi-input single-output circuit F. We can easily construct new circuits G and H that represent the new functions g and h, respectively, by assigning constant values to some inputs in the original circuit F. Experimental results show that the proposed method is very effective as a preprocessor for a combinational circuit optimization program.
